Trying to test the application with butterknife 8.4.0 and some sample text and I keep getting a NullPointerException The actual code itself is fine but I believe Android.mk might be the issue. So here are the portions of that makefile that are under question:

LOCAL_ADDITIONAL_DEPENDENCIES += $(PROCESSOR_JARS)
